He is still young and he seemed to have a good relationship with his players so that is a great factor to consider for a team to become a championship team. SMB veterans will retire soon, this Phoenix team has a great chance to dominate if they'll continue to mold their young superstars.
That's very important, having a good relationship with the team build more trust and confidence from each other, he can pull a player anytime trusting that the player will deliver.
It's too early and coach Topex is still young, he already have all the things he needed, just now he's in-charge executions will be coming from him, unlike when he still played as assistant.
The team still have a long years to play together and just like your point about the SMB, the
stars are now getting older. Time for other team now to work harder and build the franchise
for a much better chance of getting a title.
